Engine warning light on.
 

Help,

was out for a good fast spin last night , the engine warning light came on after about 20 miles. Stopped the bike and after i cooled down, checked oil and coolant etc.
Did install a USB 3 power commander a few weeks ago but tried taking it out of the wiring and still the damned warning light is on all the time.
Its an xt660x 2007/8 model.

any suggestions?

What fault codes are listed in your dash?

Hi,

Sorry its error 24 on the display which is O2 sensor.
Now as part of a power commander install ,you disconnect the O2
sensor and plug in a dummy plug with 2 resistors in it.
Funnily when I installed the Power commander all was well and no error
24.
How can I access diags and clear this error as I think its just a misnoma!!

Worzel.
